Definitions

  • the first spring clutch 100 is constructed such that a clutch spring 100a having a substantially rectangular section is inserted in the outer surfaces of a boss 99a of the sprocket 99 and of a boss 98a of the idler gear 98, and such that a first ratchet sleeve 100b having teeth mesh with the outer surface of the clutch spring 100a.
  • a leading portion 100aa of one end of the clutch spring 100a engages with an engaging hole 100bb of the first ratchet sleeve 100b.
  • a ratchet hook 101a is swingably disposed under the first ratchet sleeve 100b and can engage with the teeth of the first ratchet sleeve 100b.
  • reference numeral 110 denotes a shaft for driving the aligning rollers 26.
  • a boss 111 is disposed at the end of the shaft 110 and is rotated together therewith.
  • a sprocket 113 and a drive gear 112 are disposed inwardly of the boss 111 and are driven by a driving source (not shown).
  • a second spring clutch 114 is disposed between the boss 111 and the sprocket 113.
  • the second spring clutch 114 has substantially the same structure as the first spring clutch 100.
  • Fig. 11 is a schematic front view of the copying machine in which the document table 3 is located in the home position; and Fig. 12 is a schematic plan view thereof.
  • the position of the document table 3 which.is indicated by the solid line in Fig. 1 is the home position.
  • a home position detecting magnet 143A is arranged at the left end of the document table 3.
  • a home position detecting magnet switch 143B is arranged on the rear surface of the upper housing unit 1A and is located below the home position detecting magnet 143A.
  • the position of the document table 3 which is indicated by the two dash line in Fig. 1 is the limit position of the direction indicated by arrow BB in Fig. 1.
  • the exposure lamp or EXPO-LSMP 4 goes on when the document table returns to the predetermined position.
  • the step corresponding to the energization of the P-STR-SOL 123 can be executed, In this case, the timings at which the exposure lamp 4 goes on differ in the first and second copies in the multi-copy mode.
  • the exposure lamp 4 goes on for the second or subsequent copies at a delay of 100 ms as compared with the case of the first copy.
  • the ON time of the exposure lamp 4 for the second and. subsequent copies is shorter than that for the first copy according to the following reasons: (1).
  • the exposure lamp is turned on in 300 ms after the M-STR-SW 138b is turned on.
  • the charger turns ON and the document table starts to -.move in the forward direction.
  • the P-STR-SW 145B is ON
  • the P-STR-SOL 123 is OFF.
  • the aligning rollers 26 start rotating, whereas other rollers are stopped.
  • the paper sheet is conveyed in the transfer section.
  • the subsequent process is the same as the routine described above to perform copying.
